TO ALL WHOM IT MAYOONGERN:

Be it known that L3. L. 'DENNEY, of Christiana, in the county ofLancastciyand State of Pennsylvania, have invented certain new anduseful Improvements in Stove-Gases for Railway-Cars; and I do herebydeclare that the following is a-full clear, and exact descriptionthereof, reference being had to the accompan in drawings, and to theletters of reference marked thereon, which form a part of thisspecification, in .which g l Figure 1 is a central section, Figure 2 aside elevation, and Figure 3 a side view of the top part of the casing,showing its valve or damper-attachment. The object of this inventionisto provide against the horrible disasters that sometimes occur from theburning of cars, when a collision has taken place, or they have beenthrown ofl the track, and the nature of it consists in securing a casingover the stove, so constructed as to deflect the heat, yet, in the eventof an accident, to prevent the escape of fire, or ignition to the car orfragments thereof.

To enable others skilled in the art to avail themselves of the benefitof my invention, I will now describe its construction.

A represents a metal casing or cylinder, provided with'apertures, (Z (Z,for the more perfect radiation of the heat. These apertures are madesufiicientlysmall to prevent the escape of coals of fire, should thecars be upset. 13 represents the base, furnished with the collar e.Through this collar-,perforations are made for thepurpose of securing itto the floor,'by means of screws, bolts, or any other eifective manner.0 represents the top or cap; and in order to guard against the escape offire through the stove-pipe hole, I provide said top with the valve ordamper 9. To this valve is attached the wcightedarm 7L, and upon eachside of said arm are the jaws 6'6. Thesejaws are constructed with aslightly flared slot, as seen in fig. 1, or they-may be a littleelastic, so that when the weighted armJL falls into the slot on eitherside, it will be retained in that position, and thus close thestove-flue or pipe-hole. It is intended, of course, to firmly secure thetop or cover to the cylinder A.

The pipe 0, in the top of the cylinder or casing, should only be ofisuificient length to contain thcvalvc, and connect with the ordinarystove-pipe. G G are two doors in the casing A, which, with thestove-door, are intended to be kept locked by the person in charge, sothat in the event of a violent shock, they will not be opened and allowthe escape of fire into the car. z'z'represe nt ribs. Said ribs areformed broad at their base, and then taper to an edge, as seen in fig.Theobject of these devices is twofold! first, they tend in a greatmeasure to strengthen the cylinder A, to which they i. are secured; andsecond, they prevent the stove from resting against the cylinder, andthus cause a more thorough radiation of heat. V

In the construction of the cylinder, as wcllas the cap and base, myintention is to inake them out of rolled iron, :Bessemer steel, or anymaterial which will combine the greatest strength with the least weight.

My invention is used as follows: I first secure the base to' the floor,then set the stove in the base, and secure it thereto. I then place thecylinder over the "stove, and secure it also to the base. Thus it willbe seen that in the event of an accident which causes the car to upset,the stove will be retained in position, while all possibility ofignition from the stove will be avoided, while the weighted arm/ i willfall into the jaws, and effectually prevent the escape of fire throughthe pipe holej.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is-- 1. The casing A, provided with ribs z 2',in combination with a railroad-car stove, substantially for the purposeset forth.

2. The combination of base B with casing A, as and for the purposedescribed. 3. The weighted arm or lever A operating inthe manner and forthe purpose specified. In testimonv that Iclaim the foregoing as my own,I afiix my signature in presence of two-witnesses.
